Hi Takashi,

Regarding
commit 7cdf8c49b1df0a385db06c4f9a5ba1b16510fdcc
Author: Takashi Iwai <tiwai at suse.de>

    ALSA: hda: generic: Add a helper for mic-mute LED with LED classdev

and this Kconfig entry:

config SND_HDA_CODEC_REALTEK
	tristate "Build Realtek HD-audio codec support"
	select SND_HDA_GENERIC
	select SND_HDA_GENERIC_LEDS

it seems that LED support is not always wanted (please see above).
I.e., user(s) would like to build a kernel without LED support at all.

Can you make it a build option?

thanks.
